A black high density polyethylene compound containing >2% well dispersed carbon black class A1 to ensure outstanding weather resistance, the added carbon black type is less sensitive to moisture despite the hygroscopic behavior due to its fine particle size.Antioxidants, processing aids and other additives are added to obtain excellent long term properties and a better processability ensuring protection against extreme external conditions, mechanical impacts and degradation by heat or UV irradiation. MP-COAT 5205 can be used up to 85°C service temperature of the pipeline when combined with the grafted adhesives. Safety MP-COAT 5205 is classified as no-dangerous material. We advise you to follow our safety guidelines and recommendations in our Material Safety Data Sheet. Typical Applications MP COAT-5205 is designed for use in (3LPE) steel pipe coating systems, suited for high temperature pipeline applications in conjunction with an epoxy primer and a polyolefin adhesive so mainly used for coating steel pipes in oil and gas applications and thus help in minimizing the potential for corrosion of underground steel pipes. Specifications MP-COAT 5205 fulfills the requirements of ISO 21809-1, DIN 30 670-S AND DNV-RP-F106 standards when the product is processed using the correct extrusion practice and testing procedures. |

| Max recommended melt temperature: < 260 °CDue to hygroscopic behavior of carbon black and such a compound will be sensitive to moisture. Even as low moisture as 0.04% can give the pipe a bad surface . Despite the fact that the type of the carbon black used in MP-COAT 5205 is of less sensitive type, storage for a long time or under unfavorable conditions can increase the moisture content. We therefore recommend drying before extrusion. For normal extrusion conditions and applications we suggest preheating and drying with a maximum preheating temperature of 90°C. |
